DISCHARGE-PIPE FOR URINALS.

SPECIFICATION forming part of Letters Patent No. 446,345, dated February 10, 1891.

Application filed November 20, 1890. Serial No. 372,009 (No model.)

T0 all whom it may concern.-

Be it known that I, LAWRENCE J. GRIFFIN, a citizen of the United States, residing at Barre, in the county of 'Washingtom State of Vermont, have invented certain new and useful Improvements in Discharge-Pipes for Urinals, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in discharge-pipes for urinals, water-closets, and analogous uses; and it has for its object, among others, to provide a simple, cheap, and efficient attachment to any pattern of urinal, or closet, slop-hopper, or school-closet. No special make or pattern is necessary,'the attachment beingVY such as to admit of its ready application to any andall urinals or closets in use. I do not ordinarily employ a tank, using direct pressure, although tank-pressure may be provided, if desired or more convenient. By my construction closets or urinals are automatically flushed and will flush themselves without any pull-handle attachment. They will iiush regularly, and by increasing or diminishing th'ejsupply will flush as often as desired. I dispense with complicated valves and other accessories which are liable to get out of order.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this speciiication, and in which- Figure l is a vertical section through a urinal with the discharge-pi pe thereof in side elevation. Fig. 2 is a side elevation of a modified form of discharge-pipe with parts broken away and parts in section to better illustrate the construct-ion. Fig. 3 is a side elevation of the form of pipe shown in Fig. l with an adjustable member.

Like letters ot` reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates a urinal of any of the known constructions, and B is the wasource-from a tank, if desired.

C is a coupling of any suitable construc-V tion for connecting the discharge-pipe to the urinal. The urinal is supported on the wall by any desired means.

D is the discharge-pipe, which, as shown in Fig. l, comprises a double siphon, the short leg a ot' theupper Siphon being connected with the urinal, and an air space or chamber b being formed between the two siphons. Two traps are thus formed, one at the urinal and the otherat the lower end of the attachment, the said air space or chamber being formed between the water-level in the two traps. W'hen first starting, the lower trap ills with water, and compression of the air between the two waters forces the water over the lower trap .and creates a vacuum on the upper water and siphons it out, and it then llls up, as before, and will siphon out. The time of discharge is regulated by the flow of Water into the iXture. v

This attachment may be formed of any suitable material-such as lead, brass, copper, iron, glass, earthenware, or other substance suited to the purpose-and may be made in various forms without .depart-ing from the spirit of the invention. In Fig. 2 I have shown one such modified form, wherein a substantially U -shaped piece E is provided, which is adjustable, connected to the other portions of the attachment in any suitable manner, one

way being shown in said Fig. 2, wherein the upper ends of the other portions are formed with enlargements or cups F, in which the legs of the U-shaped piece are adjustable and wherein they may be secured in their adjusted positions in any suitable mannersuch, for instance, by solderin g, frictional contact of the parts, a set-screw, or by any other desirable means. This adjustable portion gives the required depth of Water in the bowl and also allows the lower part of the attachment to be turned-around sidewise to tit drainpipes or for other purposes. A

In Fig. 3 I have shown substantially the sam e form of pipe as that shown in Fig. l, but provided with an adjustable U-shaped portion G, adjustable similar to that of Fig. 2 and for a like purpose. l

The forms of the attachment may be varied to accommodate it to the position in which it is to be used for urinals where the piping is IOO anda third member substantially U-shaped and adjustably connected with the parallel upper inclined ends of the two first-mentioned. 1 5 portions, substantially as shown and de scribed.

In testmon y whereof I aix my signature in presence of two Witnesses.
